Problem
When playing back an avi\mkv file (this is where I first noticed the problem) if I use win explorer or FF\IE or anything that requires me to either scroll with the mouse or use a scroll bar the AV playback stutters and there is a static type of sound through the speakers.
This doesnt happen if there is no AV playback.

Actually just checking it happens if there is any audio playback regardless of source. But here's the strange bit. If I have a browser\explorer window open full screen the noise is louder, if I make the window narrower the noise is less.

This happens under both OS's and they are on seperate drives.

The only thing I have thought of trying is another soundcard.

Any idea's?

Cheers
